SHINGLE-MQLDING MACHINE.

Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed March 27, 1908. Serial No. 423,609.

To all whom it may concern:

Be it known that I, VTILLIAM PUGH, acitizen of the United States ofAmerica, residing at Streator, in the county of Lasalle and State ofIllinois, have invented certain new and useful Improvements inShingle-Molding Machines, of which the following is a specification.

The molding machine forming the sub-' ject matter of this specificationis designed primarily for molding shingles and sheathing, and it has forits object the provision of novel means for shaping the surface of thearticle (to be hereinafter termed shingle, though it is tolbe understoodthat by the term is meant any tile, sheathing or like pro dnot) and forforming and puncturing a securing flange on said shingle.

A further object of thisinvention is to provide a die or pattern platepreferably with an undulating surface, and a roller having ribs andgrooves in such relation to the surface of the pattern plate, that thegrooves of the roller and ribs are'above the grooves of the plate. V

A still further object of the invention is to provide a pattern platehaving novel means for molding a shingle and its integral flange; novelmeans also being provided for puncturing the flange to form holes fornails or other securing devices.

With the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofpartsto be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had tothe accomanying drawings forming part of this speci cation wherein likecharacters denote corresponding parts in the several views, in whichFigure 1, is a top plan view of the molding apparatus embodying theinvention. Fig. 2, is a central longitudinal sectional view thereof.Fig. 3, illustrates an end elevation.

In these'drawings, the frame of the table is shown as comprising theL-shaped side and end sills A and B, respectively, the horizontallydisposed portions of the sills acting to support the plates 0, formingthe top of the table for containing the plastic material'to be worked.The plates C, are supported along the inner edges by the sills. D, whichare likewise L-shaped; the up er edges of the said sills D, serving astrac s on which the roller E, travels. Transversely disposed sills F,extend between the sills D, and. are secured thereto in any well knownmanner; the said sills being here shown as having their ends bent at anangle, as shown at f, f, and being in engagement with the sills D. Theortion of the tables between the sills D and F, is open except for aframe G, which is supported on a sill H, extending transversely of theopening. A tubular guide I, extends from the sill H, and a rod J, isslidable therein; said rod having its upper end attached to the frame;

The rod J, has a lever K, pivoted to its lower end, and said lever ispivoted to a link L, having its upper end pivoted to a bracket M, deending from one of the sills. The lever has its inner end held normallyelevated by the bracket is, on a lug of the tube.

The sill F is L-shape and the sill F, is preferably approximatelyU-shape. The two sides of the sill F, are perforated to receive and actas guides for the punches N, which punches extend throu h an end silland are connected by a plate a, to be pushed by an operator. The punchesmay be provided with springs n, to hold said punches normally retracted,and outward movement of the punches is limited by the shoulder n.

The frame G, is reciprocated between the sills D, D, F, and F, and saidsills also form the Walls of the mold. A pattern plate P, is applied tothe frame G, and is of such dimension as to fit the space inclosed bythe sills D, D, F, and F. The plate P, is preferably corrugated,although t e ornamental feature of the pattern plate may be varied tosuit particular requirements. nions g, Which travel on the edges of thesills D, D, and the roller is guided by reason of the engagement of theshoulders g, g With the inner surfaces of the sills D, D. The roller isshaped to operate in conjunction with the surface of the pattern plate,and has peripheral grooves and ribs respectively, reglstering with thelongitudinally disposed ribs and grooves of the pattern plate.

I claim:

1. In a molding machine a table having an opening in its top, a patternplate in the opening having an offset portion to form a flange on themolded article, punches slidable longitudinally and adapted to penetratethe flpnge, and means for elevating the pattern p ate.

2. In a molding machine, aframe comprising L-shape side and end sills,longitudinal A roller Q, has trunand transverse L-shaped and U-shapedsills respectively between the side and end sills forming an inclosure;a pattern plate supported in the inclosure, punches having bearing inthe duplicate Walls of said U-shaped sills or members and means forelevating the pattern plate.

3. In a molding machine, a frame comprising L-shape side and end sills,longitudinal and transverse L-shaped and U-shaped sills respectivelybetween the side and end sills forming an inclosure; a pattern platesupported in the inclosure, punches having hearing in the duplicateWalls of said U-shaped sills or members, a roller having trunnionsmlrfvable on the intermediate longitudinal s1 s.

4. A molding machine comprising a pattern plate means for its support oiframe-like outline embracing longitudinal and transverse L-shaped andll-shaped sills, and. punelnmembers having hearings in the parallelWalls of said U-shaped sills or members and having applied theretosprings to retain them in retracted initial position, said punch membershaving their outer ends yoked together by a common member.

In testimony whereof I alliX my signature in the presence of twowitnesses, this 25th day of March, 1908.
